NXP Semiconductors 74HC03PW,112

Overview

74HC03PW,112 from Nexperia is a quad 2-input NAND gate IC with open-drain outputs, designed for wired-AND logic, level translation, and bus interface applications. It operates from 2.0 V to 6.0 V, delivers propagation delay as low as 8 ns at VCC = 6.0 V, supports -40 °C to +125 °C ambient range, and features CMOS-level input thresholds. Used in industrial control I/O expansion and sensor signal conditioning circuits.

Technical Context

This device implements four independent 2-input NAND gates, each with an open-drain output requiring external pull-up for HIGH-state assertion. Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors. The logic function follows standard NAND truth table with high-impedance (Z) output for both LOW inputs.

It belongs to the 74HC family, ensuring CMOS-level compatibility, low static current (≤40 μA at VCC = 6.0 V), and robust ESD protection (HBM >2000 V, CDM >1000 V). Static and dynamic characteristics are fully specified across -40 °C to +125 °C, with propagation delays tightly characterized for CL = 50 pF loads.

FAQ

Can 74HC03PW,112 drive a 5 V LED directly from a 3.3 V microcontroller?

Yes - configure one NAND gate as an inverter (tie one input HIGH), connect the microcontroller output to the other input, and use the open-drain output to sink LED current through a 5 V pull-up. With VOL ≤ 0.4 V at 5.2 mA (VCC = 6.0 V), it ensures full LED brightness while isolating the 3.3 V MCU from the 5 V rail.

What is the maximum allowable pull-up voltage on the open-drain outputs?

The absolute maximum output voltage (VO) is +7 V per datasheet Table 4. However, sustained operation above VCC + 0.5 V risks exceeding input clamping current limits (±20 mA). For reliable long-term use, keep pull-up voltage ≤ VCC + 0.5 V - e.g., 5.5 V pull-up with VCC = 5.0 V.

Does 74HC03PW,112 support hot-swap or live-insertion?

No - it lacks explicit hot-swap circuitry or power sequencing controls. While input clamp diodes provide some overvoltage tolerance, uncontrolled VCC ramp-up during insertion can cause undefined states or excessive ICC. Use with controlled power sequencing or dedicated hot-swap controllers in backplane applications.

How does the open-drain architecture affect timing in wired-AND configurations?

Wired-AND introduces capacitive loading from multiple parallel outputs, increasing effective CL and raising propagation delay. At CL = 100 pF (two gates), tpd increases ~25% vs. CL = 50 pF. Derate timing margins accordingly and verify with actual layout parasitics in critical paths.
